[ Upstream commit 3cc1ae1fa70ab369e4645e38ce335a19438093ad ]
gv100_hdmi_ctrl() writes vendor_infoframe.subpack0_high to 0x6f0110, and
then overwrites it with 0. Just drop the overwrite with 0, that's clearly
a mistake.
Because of this issue the HDMI VIC is 0 instead of 1 in the HDMI Vendor
InfoFrame when transmitting 4kp30.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
